When selecting a structural steel fabricator, check what the supplied certificates actually cover. The manufacturer’s identity, execution class, welding process and validity date should match the proposed work. Mehmet Yücel Yapı Çelik publishes its original documentation so clients can review it alongside their project specification.
Read the original certificate
The welding certificate in our PDF names Mehmet Yücel Yapı Çelik Sanayi ve Ticaret Limited Şirketi at its İncesu / Kayseri manufacturing address. It lists EN 1090-2:2018+A1:2024, execution class EXC3, welding process 135 and material groups 1.1 and 1.2. Issued by GSI SLV Türkiye, the document shows a validity date of 20 June 2029. These details must be read within the stated scope; they do not extend to unspecified processes or materials.

Compare the document with your specification
EN 1090-1 concerns conformity assessment, while EN 1090-2 sets technical execution requirements. A welding certificate and a factory production control certificate serve different purposes. The designer specifies the execution class required for the project; a manufacturer’s EXC3 capability does not determine the class of every structure it supplies.
Procurement checklist
- Match the manufacturer’s legal name and address.
- Confirm the required execution class and proposed work.
- Compare materials and welding processes with the certificate scope.
- Agree how project-specific inspection and handover records will be shared.
- Clarify responsibilities for fabrication, erection and site work.
Ask for current status and scope confirmation during procurement. Keep the original document with written project clarifications rather than relying on a cropped screenshot. Certification is one element of the review; it does not replace structural design or project-specific execution responsibilities.
